Increased levels of reactive oxygen species (ROS) favor adipogenic over osteogenic differentiation in human bone-marrow derived mesenchymal stromal cells (BMSCs). Therefore, biomaterials containing ROS-suppressing elements such as Cerium (Ce) have been introduced to cell-based bone-tissue-engineering (BTE) approaches. This study was conducted to assess the efficacy of Ce-doped mesoporous bioactive glass nanoparticles (MBGNs) in reducing ROS levels and subsequently inhibiting the …
